Centerfire Systems (1-800-950-1231) has what looks like the same gun for $129, without the heat shield.
I've been curious about these guns for a while, but haven't bought for two reasons.
1. After they carried them for about a year, they advertised a bunch of them as "Gunsmith Specials" for a really cheap price. These were guns that had been sold, then were returned broken.
2. They advertised some Chinese O/U shotguns that looked really sharp, for around $129 each.
I worked with a FFL at the time, so he ordered 6 for some of us at work.
I don't know if anybody else shot theirs or not.
I took mine to the range to pattern it.
After about 12 shots, it started getting hard to break open.
After about 4 more, I ejected the empties, and the gun wouldn't close. I could see bent "metal" in the action. I sent it back for a refund.
Later they advertised a bunch of the O/U shotguns as "Gunsmith Specials".
I'm going to look for a used 870.
